Okay, I'll get really, really real.
My mother comes out in the morning and proceeds to tell me how I have not cooked the bacon right, how I forgot to take the trash down the night before as she asked, then she sits down to her plate and tells me I musn't forget to do the dishes because my aunt is coming over. She asks me will I have time please to vacuum real quick before she arrives. I get up to rinse my plate and she asks me if I will go downstairs and let her dog out. I say yes and head down the stairs. She reminds me to get the trash. When I come back upstairs, she asks me if I will take down the recycling. Meanwhile, she has finished eating, has not rinsed her plate or cared that I will have to now scrub the dried yolk off, and is on the phone laughing with someone. She holds her hand over the receiver as I walk by and asks if I will go to the store for some groceries so she can have lunch for she and my aunt. I finally explode, but the anger has been building and building and I have been murdering her because she is sooo selfish.
So, I am angry over the fact that someone is being so unjustly treated, and that person is ME! Will you say I am angry with cause?
Now, our Lord was much more unjustly treated than me, and He didn't have anger in His heart but instead said, forgive them. He forgave me of all my selfishnesses. So can it be correct that I murder my mother in anger for her selfishnesses and then say I have cause?
